Comparative Analysis of VOIP Application with Different Queuing Schemes in WiMAX Using OPNET

This paper will attempt to study the effects & performance of three queuing techniques (First In First Out Queuing, Priority Queuing, Weighted Fair Queuing) with VOIP application in WiMAX throughOPNET 14.5 simulator. In recent years VOIP (Voice over Internet Protocol) is one of the most modern and interesting technology. This work inspects the execution of VOIP […]

Opportunistic Beamforming with Wireless Powered 1-bit Feedback Through Rectenna Array

This letter deals with the opportunistic beamforming (OBF) scheme for multi-antenna downlink with spatial randomness. In contrast to conventional OBF, the terminals return only 1-bit feedback, which is powered by wireless power transfer through a rectenna array. We study two fundamental topologies for the combination of the rectenna elements; the direct-current combiner and the radio-frequency […]

Anti-theft energy metering for smart electrical distribution system

Accurate metering and billing of actual energy consumed by consumers is integral to commercial management of an electric utility. An aggregate technical and commercial loss in India is around 27% and this is very high in spite of various reforms and measures by electricity boards across country. One of the significant components of these losses […]

Application of a Packaged Fiber Bragg Grating Sensor to Outdoor Optical Fiber Cabinets for Environmental Monitoring

Outdoor optical fiber cabinets are generally installed along roadsides where environmental conditions, such as sun exposure, rain, and dust, can cause damage to the cabinets. Furthermore, high temperatures and unexpected impacts that cause cabinet deformation may damage the networkequipment inside the cabinets, affecting the quality of communications. This paper developed an optical fiber sensing system for […]

Implementing attacks for modbus/TCP protocol in a real-time cyber physical system test bed

To understand security vulnerabilities of communication protocols used in power systems, a real-time framework can be developed to conduct vulnerability studies. The framework should implement protection mechanisms against vulnerabilities and study their effectiveness. In this paper, a realtime cyber-physical framework or test bed is presented. It integrates a real-time power system simulator and a communication […]

Routing-Aware Design of Indoor Wireless Sensor Networks Using an Interactive Tool

In this paper, we present an interactive design tool that can assist rapid prototyping and deployment of wireless sensor networks for building automation systems. We argue that it is possible to design networks that are more resilient to failures and have longer lifetime if the behavior of routing algorithms (RAs) is taken into account at […]

C22. Avionics Full-duplex switched Ethernet (AFDX): Modeling and simulation

This paper develops a comprehensive simulation model for Avionics Full-duplex switched Ethernet (AFDX) network based on OPNET platform. Accordingly, the performance of AFDX networks is analyzed. The effect of frame size, switching delay and changing frames transmission order on the AFDX network performance are investigated. It is found that using faster switches and small frame size reduces […]

Minimizing resource protection in IP over WDM networks: Multi-layer shared backup router [invited]

Optical networks and Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) based networks have been traditionally designed and operated by separate departments of network operators. Likewise, both layers have always represented different business areas for system providers, which maintain different product lines for each of them. However, network operators have an IP/ MPLS over WDM architecture. The main […]

Optimized Technique for Capacitated Minimum Forest Problem In Wireless Sensor Networks

Recent advances in low power radios and sensor technology have enabled the pervasive deployment of sensor networks consisting of sensor nodes that are very small in size and relatively inexpensive. Wireless Sensor Networks (WSNs) have been seen more as a solution to large scale tracking and monitoring applications, because their low data rate, low energy consumption and […]

Experimental Demonstration of Flexible Bandwidth Optical Data Center Core Network With All-to-All Interconnectivity

This paper proposes and demonstrates a flexible-bandwidth optical interconnect architecture for data centers exploiting wavelength routing in arrayed waveguide grating routers and fast tunable lasers. The proposed architecture provides hierarchical all-to-all connectivity with low contention and dynamic interconnection reconfiguration for higher bandwidth provisioning between hot spots. An eight-cluster core network experiment testbed with hierarchical all-to-all interconnection shows […]
